Spectra - Video & Audio to Art

January 25, 2024

Maintenance update to prevent some views and controls from not displaying clearly when device is set to dark mode. Previous update: In this maintenance update internal links to internet resources, which may be displayed in the users default web browser, were changed from using protocol "http" to "https". The main difference between "http" and "https" lies in the level of security they provide when transmitting data over the internet. This ensures the security and privacy of data, protecting users from potential security threats. Additionally, many modern browsers display a padlock icon or "Secure" label for HTTPS connections, instilling trust in users.

New solid background colors available in the 'Size' pane. Be sure to select 'Include In Spectra' if desired, otherwise the selected background only applies to the editor view.

Multiple audio channel support added. Previously only the first audio channel was used. Previous Updates: Added HDR video support by converting HDR to SDR to improve colors; presents a reminder that you can set a background color for spectra videos from the Size view. 13 new presets have been added to the built-in settings library. Settings are available in the Presets tab. The Presets tab has two tables named Built-In and My Settings. These new presets appear in the Built-in settings, at the bottom. Your own settings are saved to My Settings. 126 new presets have been added to the built-in settings library. These were previously available from 'More Settings' and required individual downloads. This makes a large variety of presets readily available with ease. NEW - Shadow option in the 'Lines' pane. This option will draw shadows for every line. FIXED - After app relaunch the 'Play Waveform Audio' may sometimes play the wrong audio file. New - When saving a spectra as a video you now have the option of including the audio, if available. The video duration will then match the audio duration. This can create a fun visualization of the audio. New - Audio menu has new menu item named 'Share Waveform Audio' enabling you to send the waveform audio, if there is one, to an email, message, etc. Fixed - Issue with audio processing that could prevent a settings file that uses audio from being restored to the correct look. It was due to a slight variation in audio modulation values. This issue was caused by changes in the last version. • IMPROVED: Video color generation faster. • NEW: Apply audio or set background image from Settings. ‘Apply Audio’ for audio, 'Set Background' for background. • NEW: Playing audio shows its progress in the waveform graphic. • NEW: When switching to settings without a background from one that does an option to remove the current background is offered. • NEW: ‘Use Opened Audio’ menu item in the Audio menu: sets the current audio to the last audio imported from external apps (Files, iCloud, Messages, Music, etc) or internal samples. • IMPROVED: The audio menu items 'Use Video Audio' and 'Use Settings Audio' are reimplemented for clarity. • FIXED: Some audio files were not loading due to a mismatch of file extension and audio type. • NEW: Option apply current background color to spectra when rendering. The background color is set in the Size pane. • Other improvements. Updated 'More Settings' web view. Use 'More Settings' to load additional settings from the web into the 'My Settings' table. Fixed an issue with the 'My Settings' table where the table experienced inadvertent scrolling after selecting a setting. Updated for iOS 14. FIXED: Saving background images to the Photos library now preserves transparency. In this way restoring a background from the photos library will restore the transparency, which is important for the mask mode of the Color pane. Improved Performance: Settings data is cached to handle the increased load from incorporating background images and waveform audio files. Most notably the presets table scrolls more smoothly, but other methods that use settings data is faster. Background Preview in Settings: The background image can be previewed from the user settings table. (Swipe on a row in iOS, right(control)-click on a row in macOS.) Open Settings Options: Opening settings is more discriminate - if current settings has background, but new settings do not then an alert is presented because the existence of a background could mean the spectra does not look as expected unless you change the background settings. Play Waveform Audio: The current waveform audio file can be played (if it exists; a waveform graphic only displays the audio samples, and its presence does not mean there is an audio file associated with it.) Select ‘Play Waveform Audio’ from the Audio menu. (Or on Mac use the ‘Play Waveform Audio’ button, and in iOS tap the waveform graphic)

(Saved audio can be played from the user setting table.)
